Hi Cathy,
In the last few years, the ranges for the TSH level, which is used to assess thyroid function, have been lowered twice. Unfortunately, most labs still use the old ranges because it's expensive to set up new ranges for lab tests. The idea here is that endocrinologists will know about the changes in the TSH test. But your endocrinologist may not.
By law, you have a right to get copies of all your lab results. If you had them done at a hospital you may want to stop at the medical records department and ask for copies. If you had the tests at your doctor's office or a clinic you could ask them to mail you copies.
Many of the symptoms you're describing, including anxiety, can be caused by thyroid hormone levels that are too low. Even if levels are "within range" they can sometimes be too low for your body's needs, causing symptoms of hypothyroidism.
Thyroid eye disease, which can cause dry eye, can occur in patients with Hashimoto's thyroiditis, especially if the levels are off.
I think I'd first get copies of your labs and see if your internist or the endo have run an ANA test. If not, see if you can get a referral to a rheumatologist. I don't specifically know any doctors in your area but rheumatologists typically treat autoimmune disorders, with the exception of the autoimmune endocrine disorders, which are usually treated by endocrinologists.
A neurologist would be helpful if your doctor suspects that you could have a neurological disorder like MS, but it seems like a rheumatologist would probably be more helpful. Let me know what your thryoid function tests and blood sugar or AIC levels look like. Best, Elaine
